AT&T wireless and internet bill monthly — make sure your best card is on file. You keep every card you carry — this just makes sure AT&T renews on the one that earns the most.

Where to update it

Go to Billing & payments, then “AutoPay”.
Edit the payment method and add the card Pikt recommends.
Confirm the AutoPay change.

Make your recurring payments count.

Create your Pikt account to personalize recommendations to the cards you carry and the reward preferences you set. In Subscriptions, compare those cards for recurring bills before you change a card on file. Pikt Checkout brings the same estimate to online checkout and names the card likely to earn the most. You choose the card and pay with your own card. No credit card required to sign up for beta.
